fix(configurator): copy operator-input prompts when cloning recipe to part

_clone_subtree() in fp_part_composer_controller built node vals
manually and never copied source.input_ids — so 'Load Template'
copied the recipe tree structure but dropped every custom prompt,
leaving operators with empty data-capture screens. The fix iterates
input_ids and calls .copy({'node_id': new_node.id}) so kind,
target_min/max/unit, compliance_tag, hint, selection_options,
sequence — every field on the input model — flows through.

Verified on entech: ENP-ALUM-BASIC clone now shows all 105 prompts.
